The superabrasive material may be disposed on a substrate. The cutting face may be non- planar. The recesses and/or protrusions may include one or more linear segments. The recesses and/or protrusions may comprise dis­ crete features that are laterally isolated from one another. The recesses and/or protrusions may have a helical configuration. The volume of superabrasive material may comprise a plurality of thin layers, least two at of which may differ in at least one characterist - ic. Methods of forming cutting elements include the formation of such recesses and/or protrusions in and/or on cutting face a of a volume of superabrasive material. Earth-boring tools include such cutting elements, and methods of forming earth-boring tools in­ clude attaching such a cutting element to a tool body.
